Turn req_running into a pointer to the current bcli structure, which means
the leak detection can find it.
Also suppress leaks in the case where we're only attached to a timer

In this case, local and remote are *both* NULL; so if someone tries to
send a packet with take(), we need to free it.

I think this is what is causing #1536: getting disconnected causes gossipd to
attempt to reach the peer again, unconditionally setting the flag to tell the
master. At the same time the master also issues a reaching command (which is
allowed since it is its first), but then it clashes on the already set
flag. Setting this flag only when the master actually needs to be told should
fix this.

Addresses #486 and takes into account @rustyrussell 's
comment about PYTEST defined in the environment which
always overrides without checking the version.
During a meeting earlier this week we agreed with Eclair to temporarily
increase the final CLTV delta in our invoices to establish
compatibility with the already deployed Eclair wallets. They in turn
agreed to remove the enforcement of higher final CLTV deltas, or bump
it locally should it not match their expectations as allowed by
BOLT 11. This has since been implemented in ACINQ/eclair#627.

The fee range can sometimes cause channels to be closed when the estimator
jumps. This has been the case a few times in the last months, and causes a
number of channels to be closed, and issue reports to be filed.
Increasing this from 5x to 10x should get rid of 84%+ of these
closures (measured based on 1h windows over the last 6 months and assuming
worst case situations).

I still believe that 2 weeks is way too much, but we were promised that these
defaults would be slowly reduced to saner values as the stability increases.

Waiting for 'Disabling channel' is not enough, since it's async to the
actual tx broadcast: I caught a case where the unilateral close wasn't
in the block, and so failed.

A failed compaction shouldn't be deadly, but we should also not attempt to do
one on every gossip message after the first one fails.

`gossip_store_add` is the entry point for messages from the network, so it
should do the bookkeeping and disable on failures. `gossip_store_append` is the
shared function that wraps messages and writes it to the given file. This is
shared between the from network path and the compaction path, so we don't
directly use the `gossip_store` instance, but `fd`s.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We write both when coming from outside, as well as when compacting, so we
extract the write functionality to use it in both cases.

This makes the exposed interface much smaller, cleaner and will allow us to just
replay gossip messages from the broadcast.
